"The detainee was found unresponsive and not breathing in his cell by guards. The detainee was pronounced dead by a physician after all lifesaving measures had been exhausted," the U.S. Southern Command in Miami said in a statement. The military did not indicate how the prisoner died.
He is the fourth detainee to die of suicide at the detention camp, which opened in January 2002 and holds about 380 foreign terrorist suspects. Three other prisoners -- two Saudis and a Yemeni -- hanged themselves with clothing and bedding in their cells last June and their deaths are still under investigation by the Naval Criminal Investigative Service.
Human rights activists, who have long urged Washington to close the Guantanamo prison operation, denounced the earlier deaths as a sign of desolation while the U.S. military characterized them as acts of "asymmetrical warfare" in the war on terrorism.
Guantanamo officials have reported 41 unsuccessful suicide attempts by 25 detainees since the U.S. began taking prisoners to the base in January 2002. Defense lawyers contend the number of suicide attempts is higher.
Mark Denbeaux, a law professor at Seton Hall University in New Jersey who represents two Tunisians at Guantanamo, said he believes others there are candidates for suicide. Denbeaux said one of his clients, Mohammed Abdul Rahman, appeared to be depressed and hardly spoke during a June 1 visit. Rahman was on a hunger strike at the time and was force-fed soon after, Denbeaux said. "He told us he would rather die than stay in Guantanamo," the attorney said. "He doesn't believe he will ever get out of Guantanamo alive."
